Abstract: 薄鋼ストリップを鋳造する双ロール鋳造装置を構成する、冷却される鋳造ロール（１６）がロール支持部（１０４）に取付けられる。ロールの一方は固定され、他方は横方向に可動であり、可動ロール支持部（１０４）に作用する偏寄ユニット（１１９）により他方のロールの方へ偏寄される。溶融鋼の鋳造溜めがロール（１６）上に支持され、ロールが回転されて、ロール間のロール間隙から下方に送給される凝固鋼ストリップを生み出す。未凝固の溶融金属が、形成するストリップの凝固殻の間のロール間隙を通ってロール間隙下方で凝固するよう、ほぼ一定のギャップがロール（１６）間に維持される。偏寄ユニット（１１９）は、偏寄されたロールにほぼ一定の低偏寄力を加える効果を有する。偏寄力は、鋳造溜めの流体静力学的圧力を均衡させ、偏寄されたロールの移動に伴う機械的摩擦に打ち勝つのに必要な力と等しいと、わずかに大きいとの間でよい。これらの鋳造ロール分離力を制御することによりストリップのゲージ変動を減少できる。
